using our index, we select the appropriate file from our list set this_file to item indexof all_files Repeatwithindexfrom1to the countof all_files

the ’index’ number is of course required for the sequential renaming of our files! ’index’ is our counter that we initially set to 1 and then count up with every file. now we start looping through all selected files.

You could try to match both patterns starting with pattern with more digits at beginning, then use one replacement string that includes back-references to all capturing groups in order. This way both capturing groups exist at the same time, first capturing group always refers to 2 digits and second one to 1 digit and we don't need to deal with 4 different capturing groups. (?*? Match every thing (un-greedily) up to. Using Perl Regular Expressions there is a workaround for this using a branch reset construct (?|(.)|(.)|.) and a positive lookbehind: ^.*?(?|(\d\d)Q(\d)|Q(\d\d)(?<=(\d).)) Following Perl it expects back-references to refer to a captured group otherwise that warning is displayed. Rename uses Perl syntax for Regular Expressions. '2Q13 ABC MF PM Example_fIS.pdf' would be renamed to '2014Q23_0 ABC MF PM Example_fIS.pdf' '05Q1 ABC_IS.pdf' would be renamed to '2014Q23_0 ABC_IS.pdf' However, my rename script (using brew install rename) in the terminal provides the wrong results. My ruby code works fine: Dir.glob("*.pdf").each do |orig_name| This question helps with a single pattern, but not 2 patterns. However, I have another pattern "05Q1" which means the 1st quarter of 2005, so I would need to add 2005Q1.įiles renamed: 2017Q3_ABC-EDFGH-JLG-Sample-3Q17-fIS.pdf I need to add 2017Q3 in front of the file name. In the first file, pattern "3Q17" for example is a date that means the 3rd quarter of year 2017. Using OSX Terminal or ruby, what would be the best method to do this? It is a little more complicated because it is pattern 1 or pattern 2. I would like to match the \d\dQ\d pattern or \dQ\d\d pattern and reformat it in front of the file name.
